What are the methods of harvesting seafood?

- Involves dragging a funnel-shaped net along the ocean floor to catch fish and other marine species.

- It can be done from a single vessel or between two vessels pulling the net.

2. Dredging:

- Employs a heavy metal frame or basket that scrapes the ocean floor to collect bottom-dwelling species like clams, scallops, and oysters.

3. Purse seining:

- Utilizes a large net to encircle a school of fish and then draws the bottom closed, trapping the catch inside.

- Mainly used for pelagic species like tuna, mackerel, and sardines.

4. Gillnetting:

- Employs a vertical wall of netting that hangs in the water column, allowing fish to get caught by their gills as they try to pass through.

5. Longlining:

- Involves setting out a long horizontal line with baited hooks attached at intervals, often used for catching tuna, swordfish, and other large fish.

6. Trapping:

- Uses baited enclosures placed on the seafloor or in intertidal zones to capture crustaceans like lobsters, crabs, and shrimp.

7. Spearfishing:

- A more traditional method where divers use spearguns to target specific fish species underwater.

8. Hand collection:

- Involves manually collecting marine organisms from the intertidal zone or shallow waters, such as harvesting shellfish or seaweed.

9. Diving:

- Some seafood is collected by divers who descend underwater and gather specific species using underwater breathing equipment.

10. Aquaculture (Fish Farming):

- Involves raising fish, shellfish, and other aquatic species in controlled environments, such as fish farms or aquaculture facilities.

These methods vary based on the target species, environmental conditions, and scale of the fishing operation. Each technique has its own advantages and challenges in terms of efficiency, environmental impact, and selectivity for particular marine species.
